    Large Deformation Behavior of Long Shallow Cylindrical Composite Panels

    Get PDF
    An exact solution is presented for the large deformation response of a simply supported orthotropic cylindrical panel subjected to a uniform line load along a cylinder generator. The cross section of the cylinder is circular and deformations up to the fully snapped through position are investigated. The orthotropic axes are parallel to the generator and circumferential directions. The governing equations are derived using laminated plate theory, nonlinear strain-displacement relations, and applying variational principles. The response is investigated for the case of a panel loaded exactly at midspan and for a panel with the load offset from midspan. The mathematical formulation is one dimensional in the circumferential coordinate. Solutions are obtained in closed-form. An experimental apparatus was designed to load the panels. Experimental results of displacement controlled tests performed on graphite-epoxy curved panels are compared with analytical predictions

    Parental Motivation in Family Farm Intergenerational Transfers

    Get PDF
    An intergenerational transfer model incorporating both altruism and exchange is presented for family farm transfers. A simulation study is conducted to test parental motivation in intergenerational transfers of family farm businesses. Results indicated that family farm intergenerational transfers are altruistically motivated.Family Farms, Intergenerational Transfer, Family Farm Succession, Consumer/Household Economics, Farm Management, Q10, Q12,

    Political Polarization and Long-Term Change in Public Support for Environmental Spending

    Get PDF
    Public support for environmental protection has evinced declines in recent years that are widely attributed to growing antipathy among self-identified Republicans. Fractures in what was long considered broad and enduring support for the environment in the United States have called attention to the broader sociopolitical context in which individual opinion on the environment is formed, and especially the role of political parties and their leaders in shaping opinion. Empirical analyses of environmental support, however, remain strongly focused on individual-level correlates of support. We apply recent methodological advances in age-period-cohort models to scrutinize changes in Americans’ willingness to pay more for environmental protection between 1973 and 2014. Analyses distinguish the importance of individual traits, such as political identification, from cohort and especially period-based fluctuations that result from changing economic and political conditions. Individual-level covariate results are reflective of previous research on environmental opinion (e.g., age is negatively and education positively associated with environmental support). We further find that political context across time periods matters as much as, and interacts with, individual political affiliation to influence support for the environment. Americans of all political stripes demonstrate decreases in support for environmental spending during Democratic presidential administrations and during difficult economic times. Declines during Democratic presidencies are especially pronounced among Republicans. Analyses also highlight parallels between the high levels of political polarization in environmental support found at the end of the Obama presidency and the end of the Carter era

    A Mixed Methods Approach to Identifying Administration Issues Pertinent in Interscholastic Sports

    Get PDF
    The purpose of this study was to investigate three propositions: a) What are the administration issues most pertinent to interscholastic sport today, as well as the next five years?, b) How important are those administration issues to athletic administrators?, and c) What are the potential implications of those pertinent administration issues to practicing athletic administrators? The literature provides a general overview of relevant issues surrounding interscholastic athletics. However, the importance and implications of relevant issues to practicing high school athletic administrators are difficult to discern. To answer the first proposition, the Minnesota State High School League (MSHSL) provided 10 contemporary administration issues that were most pertinent to interscholastic sport today, as well as the next five years. To answer the second proposition, a Likert-Scale was created so that practicing athletic administrators could rate each issue on a scale of 5 = extremely important to 1 = very little importance. A national study was conducted with athletic directors from the National Interscholastic Athletic Administrators Association (N = 170) annual conference. A one-tailed ANOVA was executed to determine significant differences among the 10 administration issues identified by the MSHSL. Four issues were found to be significant; Athletic Facilities, Athletic Training, Health Issues and Travel Teams. A Games-Howell post hoc was executed to determine significant differences across geographical regions of the United States. For the third proposition, semi-structured interviews were completed to provide insight on the implications for practicing athletic administrators. The results offer insight from which further investigations could be conducted to continue building on policies that influence interscholastic athletic administrators’ day-to-day accountability when overseeing their athletic programs
